An Introduction to Makeup Water for Industrial Water Systems

COURSE NO: H03-006
An Introduction to Makeup Water for Industrial Water Systems
Course Highlights

This online engineering PDH course provides an introduction to the techniques and methods for treating makeup water used in industrial water systems.


Many installations use fresh water and, often, potable water. Makeup water, often referred to as "makeup," is fresh water that is added to an industrial water system to replace water lost by blowdown, evaporation, wind drift, leaks, steam, humidification, or withdrawal from these systems. The usual source of makeup water is the installation's potable water supply. This source is water that has been conditioned and is usually of a very uniform quality from day to day. Other sources of makeup water could include groundwater obtained from shallow or deep wells, or surface water from streams or holding ponds. These sources are not treated to the extent that the potable water source is treated. Still another source is reuse water (i.e., water that is "used" and reclaimed and not rated as potable).


This 3 PDH online course is intended for mechanical engineers, civil engineers and other design and construction professionals seeking an introduction to makeup water and makeup water treatment for industrial water systems.
